Crazygirl just posted about tropical storm Arlene. That gave me the perfect chance to try out Megatrack for OSX after having it downloaded for a while. The image below was taken from its jpg capture option then I cropped it in PhotoShop. She also linked to the National Hurricane Service, where you can subscribe to the XML Feed to get updates, very nice of them.
A shot of Tropical Storm Arlene taken form Megatrack today.
